OBJECTIVE: Although cor pulmonale due to chronic lung disease was not uncommon, there was uncertainty in its diagnosis due to the difficulty in measuring functional and anatomical changes of right heart and pulmonary vascular system. Among various non-invasive diagnostic methods presented so far, no ideal standard diagnostic criterion has been established. The authors attempted to know positive diagnostic ratio of cor pulmonale and to study the presence of the relationship between these diagnostic criteria when electrocardiographic and echocardiographic diagnostic criteria for cor pulmonale were applied to the patients with chronic lung disease. And we investigated the usefulness of echocardiogaphic diagnostic criteria for the diagnosis. METHODS: One electrocardiographic and two echocardiographic diagnostic criteria were applied to 38 patients with chronic lung disease(21 pulmonary emphysema and 17 chronic advanced pulmonary tuberculosis) for the diagnosis of cor pulmonale. Comparison was also made in their relationship. Then pulmonary artery diameter, measurement of pulmonary function test and echocardiographic examination and radio-nuclear right ventricular ejection faction were compared between the groups to ensure each criterion was satisfied. RESULTS: 1) When the three diagnostic criteria for confirming the cor pulmonale, electrocardiographic rriterion(right ventricular hypertrophy), right ventricular dimension criterion(right ventricular end-diastolic dimension>25mm, RVDd>25mm), and right ventricular wall thickness criterion (right ventricular wall thickness>6mm, RVWT>6mm) were applied to the patients, the positive rate were 32%(12/37), 30%(10/33) and 17%(6/36) respectively. A statistically significant correlation between electrocardiographic criterion and right ventricular wall thickness criterion was found to exist. 2) Various parameters of pulmonary function test and echocardiographic examination were compared in the patient groups with and without cor pulmonale when each non-invasive diagnostic criterion was applied to all patients. Followings are the results. (1) In the positive group on electrocardiographic criteria, vital capacity, forced vital capacity, and arterial oxygen tension were significantly smaller than in the negative group on electrocardiographic criterion(p<0.05), and the echocardiographic parameters of right ventricle, ie. end-diastolic area, end-systolic area, end-diastolic dimension, end-systolic dimension, mid-ventricular short axis and maximal short axis in positive group were significantly larger than in the negative group. (2) In the positive group on right ventricular diastolic dimension criterion(RVDd>25mm), percentage forced expiratory volume in 1 second and forced expiratory flow 25-75% were significantly smaller than in the negative group on right ventricular diastolic dimension criterion. (3) In the positive group on right ventricular wall thickness criterion(RVWT>6mm), vital capacity, forced vital capacity, forced expiratory volume in 1 second, forced expiratory flow 25-75% and arterial oxygen tension were significantly smaller than in the negative group on right ventricular wall thickness criterion. CONCLUSION: When several non-invasive diagnostic criteria for cor pulmonale were applied to the patients with chronic lung disease, there were some differences in its positive diagnostic ratio depending on the applied diagnostic criteria. There was also a statistically significant correlation between electrocardiographic criterion and right ventricular wall thickness criterion. When each diagnostic criterion was applied to the patients, significant differences were found in several parameters resulted from pulmonary function test and echocardiographic examination based on presence or nonpresence of cor pulmonale. But no difference in the ejection fraction measured by radio-nuclear method was shown between cor pulmonale group and non cor pulmonale group. Consequently it was suggested that applying echocardiographic criteria in addition to electrocardiographic criterion for the diagnosis of cor pulmonale in the patients with chronic lung disease is clinically useful.

2.Current Concept of Management of Partial-thickness Rotator Cuff Tear.
Clinics in Shoulder and Elbow 2014;17(4):209-217
Most studies on the pathophysiology, natural history, diagnosis by imaging and outcomes after operative or nonoperative treatment of rotator cuff tear have focused on those of full-thickness tears, resulting in limited knowledge of partial-thickness rotator cuff tears. However, a partial-thickness tear of the rotator cuff is a common disorder and can be the cause of persistent pain and dysfunction of the shoulder joint in the affected patients. Recent updates in the literatures shows that the partial-thickness tears are not merely mild form of full-thickness tears. Over the last decades, an improved knowledge of pathophysiology and surgical techniques of partial-thickness tears has led to more understanding of the significance of this tear and better outcomes. In this review, we discuss the current concept of management for partial-thickness tears in terms of the pathogenesis, natural history, nonoperative treatment, and surgical outcomes associated with the commonly used repair techniques.

OBJECTIVE: Our purpose was to investigate the relationship between the levels of IL-6 and tumor necrosis factor-alpha in the peritoneal fluid(PF) of women with and without endometriosis and infertile women. Design: Prospective and case-control study. Setting: University hospital. Patients: Twenty-nine women with laparotomy or laparoscopic findings of minimal to severe endometriosis, and twenty-eight women with no visual evidence of pelvic endometriosis and with benign gynecologic disease. Main Outcome Measures: PF IL-6 and tumor necrosis factor-alpha levels were determined using commercial ELISA. IL-6 and tumor necrosis factor-alpha concentrations were compared among women with and without endometriosis, and with infertile and fertile women, and then also compared according the revised American Fertility Society classification. RESULTS: IL-6 and tumor necrosis factor-alpha concentrations were higher than in the PF of women with endometriosis than in matched normal controls. Cyclic variations in IL-6 concentrations were seen in PF from patients with endometriosis: the concentrations in the secretory phase were significantly higher than those in the proliferative phase. IL-6 concentrations were higher than in the PF among of infertile women than in fertile women. A significant correlation between PF IL-6 and tumor necrosis factor-alpha concentrations and endometriosis stage III and IV was noted. CONCLUSIONS: Increased PF levels of IL-6 and tumor necrosis factor-alpha in patients with endometriosis may be relate to endometriosis-associated infertility and to the pathogenesis of endometriosis suggesting that partially contribute to the disturbed immune regulation observed in patients with endometriosis.

Involvement of the vena cava by direct vascular extension of renal cell carcinoma occurs in approximately 5% of patients undergoing nephrectomy for this neoplasm. While successful, removal of caval neoplastic thrombi has been reported occasionally, it has been general impression that renal cell carcinoma extending into the vena cava carried an extremely poor prognosis. A 45 years-old male patient was admitted with painless gross hematuria and palpable mass on fight upper quadrant. Surgical exploration was done through 10th thoracoabdominal incision. A right nephrectomy and retroperitoneal lymph node dissection were done for renal cell carcinoma. It was evident on palpation that the tumor was in the It was evident on palpation that the tumor was in the inferior vena cava Partial resection of the inferior vena cava and removal of intra vena cava thrombus were performed. This patient has led a normal life for 18 months following surgery without clinical evidence of tumor. And so, we were presented with review of the literature.

Genes of cancer-associated testis antigens (CTAs) are expressed in various cancer tissues. In order to use CTAs as cancer diagnosis marker, we developed molecular method for detection of CTAs transcripts in tissue. In order to know the applicability of DNA of cancer-associated testis antigens (CTAs) on cancer diagnosis, molecular diagnostic methods for detection of gene expression of melanoma antigen gene (MAGE), GAGE, and B melanoma antigen (BAGE) was studied. After comparing DNA sequences of CTAs, S1/AS1 and S2/AS2, GAGE-S/ GAGE-AS, and BAGE-S/BAGE-AS primers were designed for the detection of MAGEs, GAGEs and BAGEs, respectively. The gene expression of CTAs in cancer cell lines, head and neck cancer tissues, ovary cancer tissue, and peritoneal cells of gastric cancer patients were investigated by reverse transcription-polymerase chain reaction (RT-PCR) using these primers. The MAGEs, GAGEs and BAGE genes were expressed in 8/8 (100%), 5/8 (62.5%) and 1/8 (12.5%) of head and neck cancer tissues, respectively. The gene expression of MAGEs were also detected in 8/10 (80%) of ovary cancer tissues and in 9/10 (90%) of peritoneal cells of gastric cancer patients in RT-PCR test using S1/AS1 primers. The results of this study suggest that molecular diagnosis method using CTAs genes, especially RT-PCR using S1/AS1 primer combination, is useful for diagnosis of cancer and it will be used for the prediction of cancer progression or regression and metastasis in future.

A 60-year-old man with advanced esophageal cancer was admitted for surgical placement of a feeding jejunostomy tube before commencement of chemoradiotherapy. His esophageal cancer had directly invaded the posterior tracheal wall, inducing a nearly total obstruction of the distal trachea. On the day before the surgery, respiratory failure developed due to tumor progression and tracheal edema. Tracheal intubation and mechanical ventilation were attempted without success. Application of veno-venous extracorporeal membrane oxygenation (ECMO) corrected the patient's respiratory acidosis and relieved his dyspnea. With full ECMO support, he underwent tracheal stent insertion. Two hours later, he was weaned from ECMO support uneventfully. This was a successful case of tracheal stenting for airway obstruction under rescue veno-venous ECMO.
